Can the Medication response (PGx) test help me switch from another treatment?

The Medication response (PGx) test is a source of information, not a treatment you switch to. It checks selected genes that affect drug metabolism. For some medicines, this information may help a clinician consider a dose change or a different option. Results vary. It does not assess every medicine or every reason a treatment may not work well.

If you want to change treatment, tell your clinician what you take, how long you have taken it, and why you want a change. Share any side effects, missed doses, and past treatment trials. Ask whether the test includes genes relevant to the medicines being considered. Different PGx tests can cover different genes and variants.

A licensed physician in your state decides whether ordering this test is appropriate. Any treatment switch needs its own clinical review. Your treating clinician may recommend a taper, a waiting period, or follow-up depending on the medicines involved. Keep your current plan until you receive clear instructions. Do not combine old and new treatments on your own.
